Alfasud ti QV - cam belt 98 teeth or 100?

[Mike]

Might sound like an odd question, but I have just bought a 12/1983 sud ti.  It has sat for years in dry storage, and prior to turning the key, I'd like to replace the cambelts.  Thing is, when I called Turin, I was informed that 1.5liter engines had both 98 and 100 teeth belts and I would need to count them first. 

It this true?  It sounded rather odd at the time.

Cheers

PS...a sud ti has been on the bucket list ever since my first car (Fiat 128 3P) met its maker and I test drove a sud as a replacement.  I never bought the sud (terrible rust issues) but I never forgot the drive!

The plot thickens...have been advised that is could be due to hydraulic/non-hydraulic tapets, but then advised by Joe at Turin that he has seen variants on this theme...hmm from the factory or perhaps later mix and match of parts from Alfisti....

I've ordered a 98 tooth belt and have crossed my fingers...!  Still keep for wise input / eperience as I have not seen this topic touched on on this board.  Would be good to get closure.

The 1500 cc Boxer Motor only came out with solid tappets, the 1700 had hydraulic tappets, HOWEVER....the first 200 1700's that came to Australia had 40 IDF carbs and solid lifters, because according to urban myths, the Hydraulic parts were not ready, so the first batch were solid.
I tried to get a 1700 carb motor for the Sud, but all had hydraulics and Fuel Injection, so i had to wait about 5 years until a carby 1700 came up at Milano Spares in Thomastown, then a bloke i know beat me to it, and i had to wait a few more years.
The 98 tooth and 100 tooth may be for solid / hydraulic, the one with 98 tooth would have the cam closer to the crankshaft, as the belt would be shorter, will check my old belts for no of teeth, Colin.

I can confirm that a mates 87 sud sprint with 1.5 boxer on twin carbs has 98 teeth, and is not hydraulic.  I think that settles it, sud ti QV 1.5L would have 98 teeth....will confirm on weekend.

Colcol, really appreciate the input, I can see you are the sud goto guy :-)

I agree.. My memory says a 1.5 carb motors had 98 teeth.
Early suds had a different water pump got the fella earlier who was confused.


That said... Which final version of the boxer engine gave the best drive ability, torque and crackling lift off .. 1.7 injected or 1.7 carb??

And people used to say Sud's were sweet but toothless.....

[Mike]

Well they still could be missing a couple....

Just to close out this thread:

I can confirm that the 12/1983 Alfasud ti QV I have has 98 teeth on the cam belts.

Cheers the help.

Craig, the 1700 carbs were a more simple swap, the injected needed electric fuel pumps and computers and special aircleaners to suit the EFI, the carb engines went straight in.
The carbs had more power and more fuel consumption, the EFI had better emmisions compliance and lasted longer......because the carbs used more fuel that used to wash the oil off the bores and cause accelerated ring and bore wear, the 1700 carbs used 40 IDF webers that were rare and used to get stolen for HDT Commodores, Mazda's and Datsuns, a wrecker told me he used to get them stolen off cars at weekend, had to take them off the car and put the carbs under lock and key, for mine i ended up with 2 Right hand side carby's that i had to convert one to Left hand???
The 1700 was a great motor with bags of torque, that ended up making me too lazy, you could pull 5th gear at about 40 kph, where my 1500 33 won't look at 5th until you are doing 60 kph.
The twin carb Alfasud remains my all time favourite Alfa Romeo, looked great and had bucket loads of personality, Colin.
